摘要:本文重点介绍贵州地区某天主教堂砖混结构的抗震分析与加固设计。经检测,建筑使用过程中,教堂大门洞口位置左上角出现超过5mm裂缝,教堂大门正对后侧墙体出现通长的竖向裂缝,采用YJK分析抗震弹性计算结果,根据检测及计算结果选用最优的加固设计方案,通过对关键构件进行加强措施,以保证关键构件满足良好的结构整体性及抗震性能要求。此外,本文系统介绍了既有砌体结构建筑安全性检测鉴定的流程,针对上述建筑缺陷及抗震不足提出的加固方案,经济简单奏效,旨在为解决其他类似的工程问题提供参考。
Abstract: This article focuses on the seismic analysis and reinforcement design of a brick concrete structure of a Catholic chureh inGuizhou region. Afier testing.it was found that during the use of the building, a crack exceeding 5mm appeared in the upper left comer ofthe church gate opening, and a full-length vetical crack appeared on the wall directly opposite the church gatc. YJK was used to analyzethe seismic elastic calculation results,and the optimal reinforcement design scheme was selected based on the testing and calculationresults. By strengthening measures for key components, it is ensured that they meet the requirements of good structural integrity and seismieperformance. In adtition, this article systematically introduces the process of safety inspection and appraisal for existing masonry structures,and proposes reinforcement plans for the aforementioned buildting defects and seismic deficiencies. It is economical, simple, and effctive,aiming to provide reference for solving other similar engineering problems.
